The component of an atom that possesses relatively little mass, thus being negligible in calculating the atomic mass number, is the:

Urea is a nitrogenous waste product that is produced when the liver breaks down proteins and amino acids. It is then excreted from the body via sweat.

The vermiform appendix is a small, finger-like projection that extends from the cecum, which is the first part of the large intestine.

Fertilization occurs in the fallopian tube and not in the ovary, uterus, or cervical canal.

The kidneys are the primary organs involved in the excretion of nitrogenous wastes. Nitrogenous wastes are mostly products of protein metabolism in the liver. One of the common nitrogenous waste products is urea, which is excreted through the kidneys.

Concentration of H+ in the solution = 10 −1 M

pH= -log(10 −1)

pH= -(-1)

Uracil is the nucleotide that is only found in RNA. The other nucleotides are found in both DNA and RNA

Exocrine glands secrete their products into ducts that carry them to the target organs. In contrast, endocrine glands secrete their products directly into the bloodstream, which carries them to target cells throughout the body.

Correlation does not imply causation. Even if two processes are found to be correlated, it does not necessarily mean that one causes the other. It could be that they are both influenced by a third factor, or the correlation could be coincidental. Therefore, the study does not indicate a causal relationship between the processes.

Lysosomes are membrane-bound organelles that contain lysozymes that are responsible for breaking down waste materials and cellular debris through intracellular digestion. This process helps maintain cellular health and homeostasis by recycling and degrading cellular components.
